x86: Expose thread features in /proc/$PID/status
Applications and loaders can have logic to decide whether to enable
shadow stack. They usually don't report whether shadow stack has been
enabled or not, so there is no way to verify whether an application
actually is protected by shadow stack.
Add two lines in /proc/$PID/status to report enabled and locked features.
Since, this involves referring to arch specific defines in asm/prctl.h,
implement an arch breakout to emit the feature lines.
